Elimination using addition and subtraction
6x-2y=32
4x-2y=18

x=7, y=5

Step-by-step explanation:

6x-2y=32

4x-2y=18

Subtract the second equation from the first equation

  6x-2y=32

-  4x-2y=18

 2x      = 14

Divide each side by 2

2x/2 =14/2

x=7

Now substitute x=7 into the first equation to find y

6*7-2y=32

42 -2y = 32

Subtract 42 from each side

42-42 -2y = 32-42

-2y = -10

Divide each side by -2

-2y/-2 = -10/-2

y =5

can i see the following ?

step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables
